SHOE-BOTTOM FILLER MCHINE.

Application ilcd April 19, 1923.

To all lwhom 1I?? may concern:

Be it known that I, Gnoiien H. MAX- WELL, a citizen ot' the UnitedStates, and a resident of Phoenix, county oit Maricopa, and `State otArizona, have invented a new and i'iseiul Shoe-Bottom Filler Machine, ofwhich the following is a specification.

My present invention is an improvement in the type ot' apparatuscontained in my application Serial Number 560,800 tiled May 13, 1922,now matured in Patent 1oi2,299 granted Oct. Q1, 1924, ifor use inlilling slioe-lnittonis with heated or heatsoftened and plastirI liller,my principal object being to render the tormer apparatus better adaptedto the varying conditions of l'iller and factory and capable of meetingihe varying speed requirements of different operators. To this end, lmake the dry h' at and the moist heat separately regulable, so that moreor less moisture may be admitted to the iillei in the reservoir Withoutvarying the heat oif the Work basin, and vice versa. As stated in myprevious application above mentioned, my main object is io promote speedand efficiency Withoutdanger or injury to the iiller, and accordingly ihave provided means for always maintaining between the source ot heatand the 'filler reservoir and work-basin a safety barrier, spare, orchamber which precludes the possibility ot a burning heat directlyagainst the liller. In the apparatus of Patent 808.297 for instance,which has been and still is the form ot' apparatus in general use inshoe factories, the steam jacket is directly next to the filler, and asthe steam pressure varies greatly iii different shoe Jfactories therehas always been a. great danger oi burning the filler in those shoefactories using high steam pressure. To make this impossible in mypresent invention and yet at the same time promote speed of melting theiiller. i niountthe steam chest close to the iller reservoir and yetsufficiently removed 'ti'om said reservoir to provide between the steamchest and reservoir a heat disseminating space suflicient to prevent adangerous localizing of the heat at any one spot/or small area ivliichwould otherwise he liable to burn the filler. ln case a steam chest isnot used. but other lrinds of heat, as YAfoil instance an electricheating` unit or units, the unit is kept out of direct contact with thebottom ci' the reservoir sufiicicntly Serial No. 633,148.

reservoir above said dry chamber, High speed, coupled vitli safety, inmelting and conditioning the filler and in rem ving and using the same,and economy or current or other source of heat are secured not merely byusing high heat and vsteam but by balancing the tivo and using them inthe right place at the right time and to the right extent. Byconcentrating tne source ot' heat and the region of effort orapplication at and adjacent the bottom ot the worlr-basin and the bottomof the mass ot filler and by bringing the moisture treatment all overand through the lower end oi the filler mass simultaneously ivith thedry heat attack on the basin and on the bottom ot the reservoir itbecomes possible to get the high speed sought and yet with satety. Bythus driving steam into the entire bottom region at a sufficient numberot points simultaneously with the quick high heating ot the supportingmetal, no charring or scorching can result because each and all theparticles ol the contacting and adjacent filler are moisture coated assoon or before the metal reaches its high heat. At the start the Ellerand metal being cold and the steam usually quite Wet the filler may tendto get too Wet before the metal gets properly hot. Hence the advantageof having separate control of the steam delivered and the dry heat. isthe iller melts and is heated and as the metal gets hot and the steamgets hotter and drier, further relative adjustment may be desirable andsometimes necessary. From the concentration of the heat generation andapplication in the bottom ot the apparatus and applying its maximumeliicienry at the lower end of the filler mass three advantages result,viz, safety Ytrom burning as just eX- plained, speed due to the sateemployment ot a high heat which was be'tore impossible, and economy ofenergy (electric current or other source) due to the' simultaneousemlli) ployment of both kinds of heat and their employmentsimultaneously coeXtensively with and throughout the whole vbottom ofthe mass and due to the progressive' endwise melting and use of thefiller so that it loosens most and is Imost easily penetrated by thesteam at the region of use. At the point. where the iller is used andhence tends to fall away and openv orloosen down, l deliversimultaneously hereand there jets or blasts ofmpenetratingdisintegrating steam, the machine holding the massseparatedbyatsyhotpartitions into relatively smalljsegregated portions so that it Ycannotmassor pack together'but must fremain instantly ready for f fastestconditioningand surestfl maintenance. fthus, and therefore quick use.`These small segregated portions are simultaneously attacked with steamand preferablywith both steam and :dry heat and'ibothlthefmetal and theadjacent filler arel simultaneously treated at Aall pointswl'ierefthehot metal would otherwise burn the filler, with thegreatresultant advantagel that both metal and filler are kept safelymore highly heated and conditioned and' by the samesimultaneousapplications andfrom-thesame source of heat (as dry heat tof'theunderside of the metal bottom :rnd-'as we'tl'heatto the upperside ofsaid bottomand the whole contactingarea of filler) than-Was beforepossible.

'In the accompanying drawings, I have .chown my invention in twopreferred'l embodiments, although it will be understood that 1 amnot-restricted thereto, as a wide range of embodiments is within thepurview of 'this application.

'Fig4 8 is' a vertical sectional detail on a reduced scale, taken on'theline 3-1-8, Fig. 7.

Referring .first to that formof the apparatus which is heated wholly bysteam, shown in 1 to 4, I mount'a steam chamber or .heater plate 1 on abase or'top flange 2 of a pedestal 3, and on said plate 1,.a fillersupply reservoir land work-basin 5. The parts 4 and 5 are preferablymade in one casting or piece and heat jacketed at 6; A cove-ri i'shingedat 8 and a two-piece, slide door 9, 10` closes the' front, while a usuallilllcr laying or condensing rolll 11 and a vand extending over thework-basin.

knife-block 12 are mounted at .one side of Radiators in the-'form'ofheat-transmissionv flues or radiators 13 (using these terms as definedin the aforesaid application), shown indetail in Figs and 6, as havingan open lower end with an opening for the admission of the'h'eat orsteam and a front bottom opening for the transmission of the steam' outinto the filler. and otherwise closed or imperfo-rate, are provided toextend up into and' through the filler mass in the reservoir tointroduce dry radiant heat into the upper part ofthe filler mass andmoist heat into the bottom of the ililler mass,

-thence to percolate Vupward through said mass. This main constructionand arrangement of parts is in general the same asgin my aforesaidapplication. A

"f'he. heater plate 1 is spaced a short distance-from the bottom of :thework-basin 5 so as to provide aheat disseminating space or chamber torender the heat all aroundthe basin uniform and prevent localizing undueheat at any one spot or region which-would burn the'filler. ln'speedingup theluse of this heat-treated filler,'there isdanger of burning, orover-heating thefillenand one of thefimportant aims of` my invention isto minimize or conteract this danger. This provision for evening theheat permits "a maximum heat without danger of drying Y out and charringor burning the fillerl because 1t maintains all the mass of lilleruniformly hot and melted and moist.

`A s'teaminlet` pipe 14 connects with the preferably a separate branchand dischargeV end or nozzle 23 for each radiator, and controlled by ahand-valve 241. A two-way valve 25 at the junction of rthe inlet pipe14, pipe 16 and a connection 26 from pipe 15 ycontrols the steam supplyto the main heater or steam chest 1, Vwhen desired. An

inwardly slant-ed shelf 2?' supports the pipe` standards 17 and 19 vinposition to direct all drippings of filler from the roll 11 or block 12back into the work-basin. The knife block is placed back and slightlyinward of the roll and` has flaring upper and lower parallel mouths? 28,29 to receive twoknives or spatulas (not shown) directly against theheater 18. A flange 30 of the inclined back portion 31 of the"bottomf32surrounds an opening 33 in the latter to prevent any accidental escapeot filler below the bottom7 and the opening 33 is shown as relativelylarge to admit a copious melting heat ito the radiator even though thesteam may be shut ol from pipes 21. In the. top side or the steam chestis a long shallow depression 34 to catch any condensation from theradiators 13 or pipe 22 and convert it instantly into steam again. Theunderside of the steam chest 1 and the base plate or flange 2 are soshaped as to provide a. deadair chamber 35 to insulate the steam chest,thereby conserving the heat and protecting the operator.

In Fi gs. 7 and 8, l have illustrated my improvements adapted toelectric heat and control. The main heating unit or units 36 are mountedon the bottom 37 of an outer casing 33 which contains and supports allthe rest ot' the machine. An inner portion preferably of sheet brass orother sheet metal extends forward to constitute a work-basin 39 andrearward and upward to constitute the hopper or reservoir 40. To thisare secured the radiators or tlues 41. rlhe heater 3G is at such adistance below said inner portion as to distribute the heatl therefromthrough the air before reaching the parts 39 and 40 and hence to avoidlocalizing the heat in one spot which would burn the liller. Thisconstitutes a heat disseminating space or chamber with the same functionand advantage as already explained in connection with the iirstdescribed form of my machine (and is a continuation, in this teature.ot' my aforesaid application). A water tank is pivoted at 43 on bracketsat the back ot the reservoir and held upright by a hook 44 beingconstructed and operating as in n'iy aforesaid application in well-knownmanner to drip into a water seal 45. The. latter connects at 46 to aninternal water basin or steam producer 47 containing an electricimmersion-unit 48 below and within it screwed into its lower end fromthe outside of the apparatus. This location of the water basin 47 formedas an internal tank conserves the heat. utilizing to some extent alsothe heat from the main heater and permits easy clearing out through itsbottom opening. .-tt its upper end the water basin and steam producer 47has a delivery pipe tapped into it with branches 23 (the same as thcsteam machine previously described) for providing steam in thereservoir, preterably extending into the radiators or tlues 41 whencethe steam, after heating` the walls ot the dues, escapes from the bottomof the latter out into the mass ot the filler in the reservoir. As.however, the main Jfunction ot these radiators is to radiate dry heatwithin the body of the {iller in the reservoir, it will be understoodthat the desired dry heat may be Obtained from the dry-heat space below,and the steam carried directly into the reservoir rather than throughthe radiators. ln order to keep all moisture away from the heating units36, the pipes 23 are secured with a tight joint 49 to the back of thereservoir and each flue. rlhe current-supply wires from the units 36 and4S (and from the roll and knife-block7 not shown) are led to a switchbox 50 and to separate suitable switches at 51, 52 in wellknown orconvenient manner.

ln use, the operator turns on the steam or electricity and lls thehopper with filler. As the melting or softening and disintegratingfiller begins dropping down and slumping 'forward he observes whether itis too moist. This may be the case at the start, due to the steamcondensing at the start against the colder walls and parts of theapparatus and against the cold filler, but is not so apt to be the caselater when everything is at a working heat. lf it is too moist7 he cutsoff the steam according to his judgment by the valve 24 or switch 527but without slowing down the process as the dry heat remains radiatingcopiously from the steam chest 1 or the electric heater 36. It the dryheat seems too severe, he is able to cut this down, with or without acorrespending reduction ot moisture in the filler. ln other words, he isable at all times to temper the iiller exactly as required by thepeculiarities ot' the given batch of filler he is using and by thecondition ott the weather. and by the kind of shoes he is working on7 oraccording to his speed as a workman. The heat disseminating space orchamber prevents burning or overheating the filler. The roll and knifeblock are so positioned, piped (or wired) with relation to the reservoirand the heating of the latter that a continuous high heat is maintainedtherein notwithstanding the lower heat at the bottom ot the reservoirand basin and the variable steam heat within the reservoir. All partscan be kept independently as near the high est speed efficiency as ispermitted by safety and the apparatus is simple, economical in use anddoes not require a high-grade intelligence to operate it. The tryingconditions and peculiarities of this general method ot illingshoe-bottoms are set forth at length in the Thoma Patent 1,225,372,patented May S, 19177 which (together with the process patent therementioned and dating back to 1907) marks the beginning o't the use ofsteam in this art. The Thoma machine used vapor in a cloud and wasnecessarily slow. Bakel-s Patent 1,201,674 suggests employing steam butin connection with a severe downward pressing ot' the filler under:torce to eject it under compression.
